[SP_F80M3]

Hello, I'm very new to datalogging and reading these numbers. Can someone tell me how everything is looking? I have a 2014 M235i RWD auto with a drop in k&n filter, JB4 on map 5, and VRSF ** running on 91 oct mixed with e85 making it around the ballpark of e30. I did a few pulls in manual, sport + mode. How do my numbers look so far? Is my boost supposed to be around 12-13psi? I thought map 5 had higher target boost?

Do you have the EWG wire?

Yes I do. I'm also having a hard time uploading the logs I guess the forum won't accept the excel file

Here we go, got to zip the files

I would recommend you to create a datazap.me account, and use that to upload and share your logs

Hi,
Post it on datazap.

Let us know what exactly you are trying to monitor

Take a look at this, made it to help in situations like this.

Here's the datazap logs:

I just wanted to make sure the AFR is within good range during WOT. Someone else also told me my avg ign is ~4. Is that a good or a bad thing? And is my boost at the right PSI for map 5?

Thanks badbread! I'll definitely try to give this a thorough read.

What causes the throttle closure at 6675 rpm?

I can only assume it was when I let off the throttle once I hit about 7k RPM, if that's what you're referring to. For those runs, I started off at 3k RPM and WOT til 7k and let off.

Update: I did another couple runs tonight but I changed to Map 2 to see if it's more consistent than Map 5 and to see how I like it. This time I ran in manual mode again, in sport mode starting at gear 3 at 2k RPM. I am noticing that my AFR is staying around 12.8-13.5 during WOT. Is this normal? I believe during idle, it's supposed to be 14.7 ideally so I thought

Boost overshoot. Not entirely a big deal unless it could be felt where there was a drivability or physical powerless. Plenty of turbo drive by wire cars use throttle to modulate power.

It's normal for this platform, direct injection runs leaner then typical port injection cars. These are cars are very smart and the ECU is very aware. If you were running too lean, it would throw lean codes and knock codes. And/OR you'd see significant timing reductions.

Would throttle closure due to boost overshoot negate the benefits of a boost-only piggyback (Dinan Sport or BMS JB+)?
